Research Projects/Interests

I am a hydrogeologist/geochemist working on water-rock interaction and groundwater quality.  I’m especially fascinated by the impact of energy production on groundwater.  I use a combination of fieldwork, laboratory experiments, geochemical analyses, and reactive transport modeling to assess and predict changes to groundwater flow and chemistry due to a variety of processes. 

 My research interests include: 

  • Impact of hydraulic fracturing (fracking) for oil and gas on reservoir chemistry and permeability, and groundwater resources 
  • Geological carbon dioxide capture and storage to combat global climate change
  • Mineral carbonation (turning carbon dioxide gas into rocks for permanent storage)
  • Hydrology of mantle peridotite aquifers in the Sultanate of Oman (a site of natural mineral carbonation) 

Professional Associations

  • American Geophysical Union
  • Groundwater Resources Association of California
  • American Association of Petroleum Geologists
  • National Association of Geoscience Teachers
